Reaction Steps

4M Hydrogen chloride in dioxane (1 mL, 0.25 mmol) was added to a solution of 4-(2-{3,3-difluoro-2-[4-(5-fluoropyridin-2-yl)phenyl]-2-hydroxypropyl}-1-trityl-1H-imidazol-4-yl)-1,1,1-trifluoro-3,3-dimethylbutan-2-ol and 1,1-difluoro-2-[4-(5-fluoropyridin-2-yl)phenyl]-3-(4-{4,4,4-trifluoro-2,2-dimethyl-3-[(trimethylsilyl)oxy]butyl}-1-trityl-1H-imidazol-2-yl)propan-2-ol (from previous step) in methanol (2 mL). After stirring at 70° C. for 1 h, volatiles were removed. The residue was basified with saturated aqueous sodium bicarbonate and extracted with ethyl acetate. Combined extracts were dried (magnesium sulfate) and concentrated Chromatography over silica eluting with 0-60% acetone/methylene chloride afforded the title compound. LCMS: 488 (M+H).
